- Microsecond package activation via warm daemon workers (~50μs)
82
-
- Persistent model tagging: keep full models loaded in memory and route commands repeatedly without reloads or 5-minute timeouts
83
-
- Support for Python 3.7 through 3.15 in a single environment (far beyond Conda’s typical 3.10–3.13/3.14 range)
84
-
- Concurrent multi-version package and interpreter loading
85
-
- True zero-copy tensor passing across different Python versions, PyTorch/CUDA versions, and frameworks — no JSON serialization or process boundaries required
77
+
- Zero-Overhead C-Dispatcher: Replaces the Python startup tax with a compiled C binary, routing commands via uint64_t word-loads in ~230µs.
78
+
- True Zero-Copy GPU IPC ("God Mode"): Passes raw cudaIpcMemHandle pointers between isolated PyTorch workers. Move tensors across PyTorch 1.x and 2.x instances in ~4.5ms without data ever leaving VRAM.
79
+
- Atomic Stash-Swaps via Rust FFI: Intercepts the `uv` installer's internal plan callbacks to atomically os.rename() directories in <1ms, creating instantly reversible environments.
80
+
- Deep ABI Parsing: Natively parses .so ELF sections to extract NPY_FEATURE_VERSION, automatically injecting the correct NumPy ABI bubble before C-extension initialization.
81
+
- Concurrent Python Interpreters: Hot-swap and execute across Python 3.7 through 3.15 simultaneously without containers or separate virtual environments.
